(c) Two parallel plates have an electric field between them of 5kVm 1. If a magnetic field of 1.0 T is applied perpendicular to the electric field such that an electron with a particular velocity moves in a straight line parallel to the two plates at a constant velocity (i.e. moves perpendicular to both fields without any change in its speed or direction), (i) what is the net force acting on the electron and (ii) what is the magnitude of its velocity? (d) Two 5μF capacitors and a 10-volt supply are connected in series. (i) Draw a circuit diagram. (ii) Find the steady-state excess charge at the electrode of each capacitor. (iii) Find the steady-state voltage across each capacitor.
